Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
You cannot add the data to our plugin via the REST API as we don’t have any routes for that.
We only allow the users to enable the Headless CMS support to get the metadata but you need to have that in place already: https://rankmath.com/kb/headless-cms-support/
Don’t hesitate to get in touch if you have any other questions.
Hello,
Since we did not hear back from you for 15 days, we are assuming that you found the solution. We are closing this support ticket.
If you still need assistance or any other help, please feel free to open a new support ticket, and we will be more than happy to assist.
Thank you.
